No, It is a diode, not a resistor, It is only there to keep voltage spikes from burning up the clutch coil.

My 77 Chevy c30 has no power. Jumped started it and drove it home. I turned it off then tried to restart it. No power no lights. nothing. Battery is good. An u help will be appreciated.


If the battery is good you will need to follow flow. Test light is the easiest to use. First hook light to ground and touch pos terminal,lights good next touch pos battery cable end, lights good. Next follow pos cable to starter pos terminal,lights good. Next hook test light to bat pos teminal,touch neg terminal,lights good. Then touch engine block, lights good ground. Next move test light clamp back to ground/neg side and touch alt pos terminal,lights good.if all that tests good, if all good move inside and check for power at ign switch pos term if at any time you dont find power you have wiring issue that needs to be addressed. Let me know what you find. Russ

How do I hook up this unit Two wires or four


Almost all car batteries have 2 pos and 2 neg. More precisely, 1 pos post and 1 side connector, 1 neg post and 1 neg side connector. You only usually use use one set or the other depending on what connectors are on the end of your cables. You can connect something else to the side posts if you need to, but generally only pair is used.

Convert battery cables from top post to side mount replacement ends?


If all you are doing is changing to a side post battery, just connect all the positive cables from the old pos post to the new pos holder and all the neg ones to the new neg holder. If you've already cut them all off and not sure where each wire goes, all the reds are positive, all the blacks are neg. To make sure use your continuity meter to test. Connect one meter lead to any good clean metal part on the car and test between each black wire in turn, the neg ones will show a circuit, the pos ones will not.

Sparks jumping from spark plug wires in 1995 chevy g20 van the wires are new and so are the plugs cap and rotor and coil


replace the leads with a heavier grade of lead insulation Use spacer bars to seperate the leads as the current will jump to the lead of lower resistance ( ie piston not in compression mode). Spark jumping will cause problems not the least being a blown motor through firing at the wrong time

Gauge showing low output alt only 1yr old wondering if it could be regulator or batt or wiring


if you have access to a digital multimeter, connect the meter (set to volts) across positive and neg. terminal of the battery, should read roughly 12.6 volts, close to 10 volts, battery may be going out, also test the alt output, disconnect neg term and place negative lead to battery neg post and positive lead to neg battery cable (make sure meter is set to amps) should read near the rating, if both those, then you'd want to do a resistance test, (set meter to Ohms) disconnect battery and connect meter neg to either pos cable terminal or where the pos cable connects to the alt and connect positive lead to opposite of neg, should read next to 0, the check resistance of the ground by connecting meter between batt neg cable and body of alt.

I have an 89 Jeep Wagoneer inline 6. Its not


You got the ignition cover, what you need to do an cylinder compression test and also check your injector for voltage while engine running hook test light to battery pos on neg and neg on pos, at injector harness check for pulsation, if you have pulsation elec. system ok, if good compression bad injector.if bad compression piston ring's or valve's.
